Ask the right questions
Which municipal procedure applies? What technical documents are required? Who handles registration? We discuss administrative support and agree responsibilities within the project.
Keep your installation documents
Ask for the relevant technical information, certificates, handover documents and warranty terms. These are useful for future service or expansion.
Check any tax benefits
Spain offers deductions for certain energy efficiency improvements. Eligibility depends on the property, tax circumstances, demonstrated improvement and current deadlines. Solar panels do not automatically qualify for a fixed deduction.
Check before work begins
Ask your tax adviser which measures may apply and what evidence is needed beforehand. Consult the official Agencia Tributaria information for current conditions.
